If I were you, I’d use only Windows for updating BIOS that way.
However, BIOS update may or may not help, maybe you could check from Acer about the changes.
Anyway, if you choose to update BIOS, make absolutely sure you have the correct version for your specific machine and model. Wrong version can do real harm to the machine, although I’ve seen that BIOS updater programs usually check it is suitable for the machine. Don’t however know how Acer handles checking.
